According to Food and Agriculture Organization's (FAO) Global Forest Resources Assessment 2020, an estimated 420 million hectares (1.0 billion acres) of forest have been lost worldwide through deforestation since 1990, but the rate of forest loss has declined substantially. In the most recent five-year period (2015–2020), the annual rate of ...
The assessment showed that although the rate of deforestation has slowed, the world's forest area continues to decrease. [16] Key findings include: The world has a total forest area of 4.06 billion hectares (ha), which is 31 percent of the total land area. The world's forest area is decreasing, but the rate of loss has declined since 1990.
